Years ago an acquaintance took apart his Starrett magnetic base. When he

I witnessed the problem, so I know it's true. Can anyone explain why it no
longer functioned? If so, thanks!

As a corollary to all the comments, Anyone have an idea how many thousand
ampere turns I might need to re-magnetise an old mag base after building a
good core around it?

The copper involved would probably cost more than a new mag base.
